The effect of number of kanji radical companions in character activation with a multi-radical-display task

The majority of Japanese complex kanji consist of two subword units (radicals), and each radical is differentiated according to its combinability. Radical-type frequency is defined as the number of radical companions (NC) functioning as the number of characters containing that radical. The current study is intended to address the question of whether the NC plays a role in kanji character activation under a multi-radical-display (MRD) instead of a tachistoscopic display. An MRD task was used in which the NC was manipulated and the frequency of use of the whole characters was matched on average across the experimental conditions. Participants were divided into two groups (good knowledge vs poor knowledge) according to the score of a kanji completion task. The participants' task was to select an appropriate combination of radicals to compose a legitimate character under the MRD condition. The poor-knowledge group yielded relatively more errors than did the good-knowledge group in the low-NC condition, whereas the good-knowledge group yielded more errors in the high-NC condition than in the low-NC condition. These results demonstrate the different influences of NC as metaknowledge (tacit knowledge of radical productivity) in both good and poor readers.     

Perceiving an object and its context in different cultures: a cultural look at new look

Abstract - In two studies, a newly devised test (framed-line test) was used to examine the hypothesis that individuals engaging in Asian cultures are more capable of incorporating contextual information and those engaging in North American cultures are more capable of ignoring contextual information. On each trial, participants were presented with a square frame, within which was printed a vertical line. Participants were then shown another square frame of the same or different size and asked to draw a line that was identical to the first line in either absolute length ( absolute task ) or proportion to the height of the surrounding frame ( relative task ). The results supported the hypothesis: Whereas Japanese were more accurate in the relative task, Americans were more accurate in the absolute task. Moreover, when engaging in another culture, individuals tended to show the cognitive characteristic common in the host culture.     

Should Candidates Smile to Win Elections? An Application of Automated Face Recognition Technology

Previous studies examining whether the faces of candidates affect election outcomes commonly measure study participants' subjective judgment of various characteristics of candidates, which participants infer based solely on the photographic images of candidates. We, instead, develop a smile index of such images objectively with automated face‐recognition technology. The advantage of applying this new technology is that the automated process of measuring facial traits is by design independent of voters' subjective evaluations of candidate attributes, based on the images, and thus allows us to estimate “undiluted” effects of facial appearance per se on election outcomes. The results of regression analysis using Japanese and Australian data show that the smile index has statistically significant and substantial effects on the vote share of candidates even after controlling for other covariates.     

How Single Older Men Reach Poverty and Its Relationship with Help-Seeking Preferences1

This study aimed to clarify patterns of poverty among single older men and examine this population's help-seeking preferences. Semi-structured interviews were conducted with 83 older single men in poverty. Three main patterns of poverty were identified: lifelong, job turnover, and retirement. A common characteristic among these patterns indicated that they did not recognize their difficulties as problems. Furthermore, we identified five groups of help-receiving preferences: independent, resignation, mutual-aid, other-oriented, and seeking. Among these, the independent and resignation groups were influenced by past experiences of failing to seek help, which was characteristic of the lifelong pattern type. Furthermore, the mutual-aid and seeking groups were oriented toward positive help-seeking, which was characteristic of the job turnover and retirement pattern types. However, neither group actively sought help for social isolation or lack of social support, suggesting that it would have been challenging to establish social relationships early on in life. Thus, it is important to establish initiatives that enable older people to understand their current state and to think about their future depending on three patterns of poverty.     

Temporal restriction in apparent motion of two objects by presenting multipartite subframes

Two experiments tested whether proper perception of motion can be realized with a multipartite subframe stimulus. In order to elucidate the constructive processes of visual motion, two motion stimuli were used which differed according to their hierarchical levels of reference. It was found that: (a) stable motion was perceived so long as the temporal interval between the neighboring frames comprising several subframes was held between 30 and 120 ms; (b) visual unification of subframes was properly achieved independently of the number of subframes insofar as the temporal constraint mentioned above was satisfied; (c) when stimuli consisted of two motions of different hierarchical level of reference, perception of the higher-level motion required the prior perception of the lower-level motion.     

Olfactory discrimination of mouse strains (Mus musculus) and major histocompatibility types by humans (Homo sapiens)

A series of experiments revealed that humans can use olfaction to discriminate closely related strains of mice, differing genetically only at the major histocompatibility gene complex (H-2). In Experiment 1, subjects were asked to distinguish between the whole-body odors of live mice. In Experiments 2 and 3, the odor source was mouse fecal pellets, and in Experiments 4 and 5, the odor source was mouse urine.     

Nussbaum’s Capabilities and Self-Determination Theory’s Basic Psychological Needs: Relating Some Fundamentals of Human Wellness

Research and theory concerning the nature and sources of well-being has been undertaken through varied approaches. Two such approaches are the capability approach and self-determination theory (SDT), both of which have postulated specific factors deemed necessary for human well-being and flourishing. In two studies we examine the relations between capabilities and well-being indicators, as well as the mediating role of basic psychological need satisfaction in these relations. Results indicate that both capabilities and SDT’s basic psychological needs are substantially associated with well-being, and that SDT’s basic needs partially mediate the relation between capabilities and indicators of wellness.     

Skin potential activity in rats, cats, and primates (including man): a phylogenetic point of view.

With rats, cats, nonhuman primates, and humans serving as subjects, skin potential activity was measured under waking conditions. In good agreement with the findings of previous workers, skin potential response waveform was always monophasic negative in rats and cats, but in humans it took three forms. By contrast, it was always monophasic positive in simian nonhuman primates, although prosimiae gave monophasic negative waves. A skin potential level-skin potential response relationship could not be observed in any subject except humans. From these results, an attempt was made to relate skin potential activity to the peripheral mechanism involved in these species on the basis of a phylogenetic point of view.     

Lateralized cognition: asymmetrical and complementary strategies of pigeons during discrimination of the "human concept"

This study was aimed at revealing which cognitive processes are lateralized in visual categorizations of "humans" by pigeons. To this end, pigeons were trained to categorize pictures of humans and then tested binocularly or monocularly (left or right eye) on the learned categorization and for transfer to novel exemplars (Experiment 1). Subsequent tests examined whether they relied on memorized features or on a conceptual strategy, using stimuli composed of new combinations of familiar and novel humans and backgrounds (Experiment 2), whether the hemispheres processed global or local information, using pictures with different levels of scrambling (Experiment 3), and whether they attended to configuration, using distorted human figures (Experiment 4). The results suggest that the left hemisphere employs a category strategy and concentrates on local features, while the right hemisphere uses an exemplar strategy and relies on configuration. These cognitive dichotomies of the cerebral hemispheres are largely shared by humans, suggesting that lateralized cognitive systems already defined the neural architecture of the common ancestor of birds and mammals.
